write a python code

You are given three separate arrays of integers say ar1, ar2 and ar3 (all taken from the user). Each of these arrays are sorted in increasing order (i.e. 1,2,3 etc.). Create a program that will return a sorted array of only the integers that are present in each of the given arrays. For example: = Example: Inputs from user: ar1 = [1,2,3,4,5), ar2 = [1,2,5,7,9], ar3 = (1,3,4,5,8) Output from program: (1,5] The numbers 1 and 5 appear in all three of the given arrays Assume the user always gives a valid input with arrays that are already in increasing order (no need to sort them prior to implementing your algorithm)
